IGNITOR UNIT (Checking with Digital Igniter Checker)

This section explains the checking procedure for the ignitor unit using Digital lgnitor Checker (special tool). With this checker, the ignitor unit can be checked either on the machine or off the machine. The following explains the checking procedure on the machine.

09931-94430: Digital igniter checker 09931-94460: Adaptor

• R emove the seats, front and rear.

• Disconnect two ignitor lead wire couplers CD at the ignitor unit.

• Prepare the ignitor checker lead wire " MODE 2" ® and adaptor ® which comes supplied with the ignitor checker

• Connect the power source leads @ to the battery. ®

CAUTION:

* Be sure that the BLACK lead is connected to the battery

8 terminal and RED lead to the EB terminal.

* Before connecting the power source leads, make sure that ®

both " POWER" button and " START" switch are in " off"....,

NOTE:

Be sure that the batter y used is in fully-charged condition.

CHECK PROCEDURE:

With all the lead wires properly connected, check the ignitor unit in the following four steps.

First Step:

Set " MODE" switch on the adaptor to " 2" position and depress " MODE 2" button then " POWE R " button. This time, " POWER " lamp should come on, if not, battery is undercharged.

Second Step:

Set " R EVOLUTION" dial pointer to " 4" position in which the checker produces the ignition primary current pulses simulating 4000 r/min of engine revolution when " START"

switch is turned on. With " START" switch is turned to ON position, check that two " MON! TOR " lamps CD and ® turn

ON. Then, turn back " R EVOLUTION" dial pointer to ".2" posi­ tion and check that two " MON! TOR " lamps CD and ® turn ON

If these lamps do not turn on and off, the ignitor unit should be

replaced.

Third Step:

Turn " R EVOLUTION" dial up gradually (assuming the engine is gradually revved up) and check that the MON! TOR lamps flash frequency as explained in the second step above increases. As the dial pointer passes beyond the graduation " 4" (4000 r/ min), the two lamps should shown continuously lighted.

When R EVOLUTION dial pointer reaches between " 13" and " 14" (13000 - 14000 r/min), MONITOR G) lamp should show

go off. This is because the ignition " cut-off " provided in the ignition system functions at 13500 ± 50 r/min.

If the lamp go off at the graduation below " 13", the engine can not perform properly and therefore the ignitor unit must be replaced.

Fourth Step:

Turn " STAR T" switch to STOP position. lfthe " IG 1" or " IG2", or both lamps remain light more than 5 seconds, the ignitor unit must be replaced.
